OVERVIEW

Welcome to PureFlow® AirDog® Fuel Air Separation, Filtration and Delivery System for the Diesel Engine

The AirDog®II Fuel Preporator® is a premium fuel pump and complete filtration system for the Powerstroke Diesel Engine. The system removes water, particulates, and entrained air from the fuel. The entrained air separated from the fuel is returned to the tank through a small return line. The fuel is then delivered to the engine at the correct pressure to meet the demands of the engine under all operating conditions.

The AirDog®II-4G systems feature a built in adjustible pressure regulator. All AirDog®II and AirDog®II-4G systems include a complete installation kit.

The AirDog®II-4G for this particular application are preset at 50-55psi from factory for a stock application. The regulator is adjustible for fine tuning the system for performance upgrades. WARNING: RUNNING THE PUMP ABOVE 75PSI WILL DECREASE THE LIFE OF THE PUMP SIGNIFICANTLY AND MAY VOID THE WARRANTY.

PureFlow AirDog products are manufactured in Shelbyville Indiana by a team of skilled workers with unsurpassed attention to detail and using the most stringent quality assurance.

TYPICAL INSTALLATION LAYOUT

The AirDog®II draws fuel from the fuel tank, removing water, particulates, and air/vapor. A regulated pressurized flow is maintained to meet the engine’s varying fuel demands. The separated air/vapor is returned to the fuel tank.

NOTE: The pictures used in this manual are for example only and may not be exactly the same as your truck.

PureFlow AirDog® AirDog® II DF-165 1999-2003 7.3L Ford Powerstroke Section 8 Initial Startup Procedure

18

INITIAL START PROCEDURE

8-1. The AirDog®II is a self-priming system, however, to prevent possible damage to the system, it is recommended to fill the water separator with diesel fuel before initial startup.

8-2. Rub diesel fuel or oil on the filter seals before installing to ensure a proper seal. 8-3. Turn the starter key to the on/run position. 8-4. While the AirDog®II is operating, bleed the fuel line to the engine of air by loosening

the fuel line connection at the engine fitting. As soon as the line is purged of air and pure fuel is observed, properly tighten the fuel fitting. NOTE: put a rag or shop towel over and around fitting to prevent splatter. Catch all spilled fuel and dispose of properly. Wear safety glasses.

8-5. Start engine. RECHECK ALL FUEL FITTINGS FOR LEAKAGE AND PROPERLY TORQUE. BE SURE ALL FUEL LINES ARE PROPERLY ROUTED TO PROTECT FROM EXCESSIVE HEAT AND SECURED TO PROTECT FROM CHAFFING AND ABRASION. RECHECK ALL ELECTRICAL LINES, SECURE AS NECESSARY.

CHECKING FOR EXCESSIVE PUMP NOISE NOTE: Each AirDog®II has been manufactured in a Quality Controlled process and wet tested for operation and performance before shipment. This is a smooth running system. With fuel or air alone, the AirDog®II fuel pump will run quietly. However, if any fuel fitting on the vacuum side, between the fuel tank and the AirDog®II or the pre-filter has been left loose during the installation process, the system may be sucking air at an excessive rate and will be very noisy. Excessive restriction in the suction line from the fuel tank can cause vapor and noise, as well. To check for these problems, unscrew the pre-filter 3 or 4 full turns and activate the AirDog®II by turning the ignition switch to on If the AirDog®II runs quietly, then excessive air from a loose fitting or leaking pre-filter seal or vapor from fuel flow restriction is most likely the reason for the excessive noise. Correct as necessary. A. The seal groove in the 3” filter is a snug fit and on occasion the seal has been found to

not be fully seated. Remove the pre-filter, remove the seal from the top of the nut plate. Clean and lubricate the seal grove. Carefully replace the seal in the grove. Be sure to fully seat the seal.

B. Check all fittings, especially the quick connect at the tank.

FUEL FILTER

WATER DRAIN VALVE

FILTER SERVICE RECOMMENDATIONS

Plugging of either the fuel filter or the water separator itself will cause low fuel pressure and low flow to the engine. If a low fuel pressure issue exists, replace the fuel filter. Typical fuel filter life is 15-20k miles depending on fuel quality.

The Water Separator Replace the water separator every other time you change the Fuel Filter or if it becomes damaged or plugged. It is suggested to check/drain the water separator every three months or as needed should you experience excessive ‘water in fuel’ conditions. When installing the water separator, be sure to clean the underside of the AirDog® base. Follow the instructions printed on the pre-filter for proper tightening procedures. CAUTION: Be extremely careful to prevent any contaminates or debris from entering the pre-filter when removing it for cleaning! Large debris will jam the Gerotor and cause the fuse to blow. This is not a warranty item. Should this happen, you can easily put the system back into working order. See the instructions on “How to clean the Gerotor” for proper procedures.

The Fuel Filter

Remove the fuel filter by turning it counter clockwise. DO NOT pre-fill the fuel filter with fuel. The AirDog® will fill the filter and prime the system automatically. Follow the instructions on the filter for proper tightening procedures. CAUTION: Dispose of waste fuel and used filters properly
